yii2中有一个有效的脚本，我无法部署它。 Docker构建了项目，一切都很好，但是如果我将docker中的nginx配置替换为nginx / sites-available / default，则会出现错误： nginx：在/ etc / nginx / sites-enabled / default：111的上游“ app：9000”中找不到[emerg]主机 我在论坛上阅读了我需要添加depends_on指令的信息： 取决于： -app 但是在这种情况下，错误开始出现在： docker-compose -f docker-compose.yml up -d
我替换了不同的版本-从“ 1”到“ 3.4”，仍然出现错误。这是最后一个： 错误：撰写文件“ ./docker-compose.yml”无效，因为： services.environment的不支持的配置选项：'XDEBUG_CONFIG' 无效的顶层属性“环境”。此撰写文件的有效顶级部分为：服务，版本，网络，卷和扩展名，以“ x-”开头。
您可能会看到此错误，因为您使用的是错误的撰写文件版本。指定受支持的版本（例如“ 2.2”或“ 3.3”），然后将服务定义放在services键下，或者省略version键并将服务定义放在目录的根文件以使用版本1。
有关Compose文件格式版本的更多信息，请参见https://docs.docker.com/compos e / compose-file /
该项目仅适用于php-7.0

帮助请为nginx和docker-compose进行正确的配置。
在yii2新手处。 非常感谢您的帮助和建议。
提前谢谢！

在顶层没有version:键的撰写文件是version 1 Compose file。这是Compose YAML文件格式的非常的旧版本，不支持网络，卷或其他现代Compose功能。您应该选择版本2或版本3。（版本3面向Docker的Swarm Orchestrator，因此对于单主机设置中的某些特定选项，您可能需要指定版本2。）您需要指定顶层version:键，然后将您需要的服务置于顶级services:键之下。
version: '3.8'
services:
app: { ... }
nginx: { ... }
mailcatcher: { ... }
db: { ... }
这实际上将直接解决您的直接问题。如Networking in Compose中所述，Compose（带有版本2或3的配置文件）将为您创建一个default网络并注册容器，以便它们的服务名称（如app）可以用作主机名。您不需要links:或其他配置。
您显示的“撰写”文件中还有许多其他不必要的选项。您无需将图像的WORKDIR重复为容器的working_dir:；您不需要expose:端口（与将ports:发布到主机不同）；用来自主机的COPY覆盖将volumes:写入图像的代码并不是一个好习惯。
在现代Docker中，您还倾向于不使用数据量容器。取而代之的是，较新版本的Compose具有可以声明命名卷的top-level volumes: key。例如，您可以将其用于备份数据库存储。
所有这些的最终结果将是一个Compose文件，例如：
# Specify a current Compose version.
version: '3.8'
# Declare that we'll need a named volume for the database storage.
volumes:
mysql_data:
# The actual Compose-managed services.
services:
app:
build:
# If the application is in ./app, then the build context
# directory must be the current directory (to be able to
# COPY app ./
# ).
context: .
dockerfile: docker/php/Dockerfile
environment:
XDEBUG_CONFIG: "idekey=PHPSTORM remote_enable=On remote_connect_back=On"
nginx:
# Build a separate image that will also
# FROM nginx
# COPY app /usr/share/nginx/html
# COPY docker/nginx/vhost.conf /etc/nginx/conf.d
build:
context: .
dockerfile: docker/nginx/Dockerfile
ports:
- "80:80"
mailcatcher:
image: schickling/mailcatcher:latest
ports:
- "1080:1080"
db:

# Use the named volume we declared above
